We have started investigating the use cases around providing a click performance report by MSCLKID. Please let us know if and how you use this report in other ad platforms today as well as how it does or does not meet your needs.

As the above points mention, most of the technology is already supported by Bing, although the crucial middle step for understanding the value of offline conversions is not supported. It is possible to upload the conversions into Bing platform, however companies who are not able to share conversion data with 3rd parties will not be able to understand the performance of the clicks. It is also important for companies that wish to build applications combining sensitive internal data.

If you need any further information on what the click performance report should look like, please let me know. I have attached a link to the relevant AdWords API documentation.
